# dkimdo changelog

All notable user-facing changes are listed in this changelog.

This project follows Rust-flavoured [semantic versioning], with changes to the
minimum supported Rust version being considered breaking changes.

[semantic versioning]: https://doc.rust-lang.org/cargo/reference/semver.html

## 0.1.1 (2024-06-14)

### Changed

* The poorly-named option `--pubkey-format rsa` is now `--pubkey-format pkcs1`.
  The old name still works and may be removed in a later version.

### Added

* The new low-level command `dkimdo crypt` performs cryptographic operations as
  used in DKIM. Together with `dkimdo canon`, this command makes it possible to
  produce and validate the body hash and signature values ‘by hand’.
* One-letter abbreviations for some command arguments (for example, `dkimdo g r`
  is now the same as `dkimdo genkey rsa`).

### Fixed

* When signing, some defaults have changed: *c=* is *relaxed/simple*, *x=* is
  five days, and *h=* now covers a more generally appropriate and documented
  selection of headers. (This technically breaking change is filed under ‘fixed’
  because the new defaults may be seen as simply more interoperable or more
  secure.)

## 0.1.0 (2024-05-21)

Initial release.
